C is the answer I used to work at McDonald’s I know military time
All elements can be classified as metals, metalloids, or nonmetals
Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation (![[\alpha]](https://tex.z-dn.net/?f=%5B%5Calpha%5D)
) = 
where, 
= observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c = 
= 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation () =
= 
= 
Thus, we can conclude that the specific rotation of this compound is .

C. The gold would float if placed in the mercury.
A. The mercury will change temperature at a much faster rate under the same heating conditions.
1. Radio isotopes are used in all the industries mentioned above, that is, nuclear power plants, pharmacology and agricultural studies. So the correct option is D.
2. The statement is true. Radio isotope is used in medicine mostly as a diagnostic tool to diagnose illnesses.
3. Nuclear wastes are enclosed in lead and buried in cement casks deep underground so that the lead, cement and the earth cover will act as radiation shield. The correct option is B.
4.This statement is false. The US has 75 different radioactive storage locations across USA.
5. This statement is false. Radioactive contamination can enter the body through inhalation, ingestion, absorption and through contact with skin or clothing materials.
6. The statement is false. Uranium fuel is not burned, it undergoes fission process.
7. This statement is true. This is because nuclear power production has less green house effects compare to fossils fuels.
8. This statement is false. Nuclear energy is not renewable and it pollutes the environment.
9. Nuclear power plants are favoured because the power produce by them are more reliable source of energy which does not deplete the ozone layer.
